Results are presented from photometric obaservations in the Stromgren uvby four-color and H-beta systems of early-type high-velocity stars in the solar neighborhood. Several types of photometrically peculiar stars are selected on the basis of their Stromgren indices and are provisionally identified as peculiar A stars, field horizontal-branch stars, metal-poor stars near the Population II and old-disk turnoffs, metal-poor blue stragglers, or metallic-line A stars. Numerous photometrically normal stars were also found. 62 refs.
